shadscale shrubland communities, and 1500 stems/acre for the <br />pinyon-juniper community. Commitment to these standards by the <br />operator satisfied the requirements of Stipulation No. 9. <br />The permittee has measured species diversity in terms of species <br />richness and species equitability and has proposed a means to evaluate <br />revegetation success in terms of species diversity in response to the <br />requirements of Stipulation No. 13 attached to the initial permanent <br />regulatory program permit. Based on a review of the applicant's <br />response to the stipulation, the Division was able to determine an <br />adequate success standard for species diversity. As a result, <br />Stipulation No. 10 was required. Submittal of Technical Revision 4 in <br />1986 by the operator incorporated the following vegetation success <br />standards into the permit: The following species diversity <br />revegetation success standard will be established for all revegetated <br />areas at the Munger Canyon Mine: three cool season grasses, two warm <br />season grasses, and two fortis be established, at minimum: no one <br />species of which is to comprise more than 40 percent of the relative <br />vegetative cover. Commitment of these standards by the operator <br />satisfied the requirements of Stipulation 10. <br />The Division is concerned with the ability of Salt Creek Mining Company <br />to reclaim the area given the low annual precipitation. The applicant, <br />in responses to Stipulation No. 14 attached to the initial five-year <br />permit, received approval for and subsequently undertook a biennial <br />revegetation monitoring program to measure the success of revegetation <br />efforts at the Munger Canyon Mine. The Division reviewed a <br />revegetation report submitted by the applicant on January 4, 1984 for <br />areas sampled during July and August, 1983. The report indicated that, <br />at the time of sampling, revegetation was successful to terms of <br />exceeding baseline values for herbaceous cover and production at both <br />sites. Based on the fact that revegetation undertaken at the mine site <br />was temporary in nature and may be modified by future activities, the <br />Division suspended the requirement for further revegetation monitoring <br />at the mine site until permanent revegetation occurs on any area at the <br />site. Stipulation 11 was attached to the permit during the 1985 Permit <br />revision. <br />Stipulation 11 required the permittee to revise the permit application <br />to include the annual revegetation monitoring program proposed for the <br />Munger Canyon Mine in the April 18, 1983 letter to the Division from <br />Sheridan Enterprises. The program will be initiated the second year <br />after initial permanent revegetation seeding of any area at the Munger <br />Canyon Mine. Submittal of Technical Revision No. 4 in January 1986 <br />satisfied the requirements of Stipulation 11. <br />Pursuant to Rule 2.07.6(2)(n) the Division has determined that no <br />threatened or endangered species of plants exist at the Munger Canyon <br />site, based on information supplies by the applicant. <br />1. The Division proposes to approve the use of introduced species in <br />the reclamation seed mix. The applicant has submitted information <br />which shows that the introduced species are desirable and necessary <br />to achieve the approved post-mining land use, and are not poisonous <br />or noxious (4.15.2). <br />-40- <br />
